Rag,
I am saying they have only offered opinion.

No. They are reporting their experiences, not offering opinions.

Jim,
We really have been here over and over again

I know. Why did you ask for it all over again?

you will never convict anybody of anything unless you specify what you are accusing them of

I am not convicting anyone of anything.
I am just reporting that Labour has a problem with anti-Semistism according to Labour itself.

If "The NEC are appalled by recent cases of anti-Semitic abuse" then you make yourself ridiculous by denying there were any.

Note Rag, they are stating facts not offering opinions.
